Built from cobalt steel, it handles harder workpiece materials and elevated cutting temperatures better than standard high-speed steel tooling. The straight-cylindrical shank seats securely in standard drill press, lathe, or CNC collet chucks. At 5 inches overall length with a 1.25-inch straight flute, this reamer is suited for through-holes and blind holes in light to medium stock. The bright, uncoated finish allows for easy wear inspection during service. Right-hand cutting direction is standard for conventional machine setups.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is used in machine shop, maintenance, and production environments where hole tolerances require finishing beyond what a drill alone can achieve. Typical applications include metalworking operations on steel, stainless, cast iron, and similar ferrous materials where cobalt steel tooling offers a durability advantage. It is installed by machinists and tool-and-die professionals using drill presses, engine lathes, turret lathes, or CNC machining centers. It is not a hand reamer and is not intended for manual operation without machine support.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReamer diameter of 0.1960 inches matches wire gauge size 9 for precise hole finishing\u003c\/li\u003e\n\u003cli\u003eCobalt steel construction provides improved heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for secure chuck or collet mounting\u003c\/li\u003e\n\u003cli\u003eStraight flute geometry suited for through-holes and most general reaming operations\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard machine rotation\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish allows straightforward visual wear inspection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a machine chucking reamer for use in drill presses, engine lathes, turret lathes, and CNC machining centers equipped with collet or drill chucks accepting a straight-cylindrical shank in the 0.1500 to 0.1999 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis reamer is installed by a machinist and requires a machine tool for proper use — do not use as a hand reamer. Power down and lock out the machine before mounting or removing the tool from the chuck or collet. Ensure the shank is fully seated and the collet or chuck is tightened to the machine manufacturer's specification before beginning the cut. Apply appropriate cutting fluid for the workpiece material to extend tool life and achieve target surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.1960 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Size)\u003c\/strong\u003e: 9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.1500 to 0.1999 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDowel Pin Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOver\/Under Size Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 72308091\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51750651330866,"sku":"72308091","price":41.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72e2e18333df4a003c3e2e1b8f028578_3d9241ac-5497-44d1-97cf-617790c9a21d.jpg?v=1788917848","url":"https:\/\/voomisupply.com\/products\/hertel-72308091-chucking-reamer-wire-9-0-1960-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
